Problems solved by technology

[0002] The light rail intermediate shaft is an important part of the light rail transmission system. It is used for the transmission of the output power of the power system. There are keyways on the shaft for positioning the transmission teeth. Larger, so the torque on the intermediate shaft is also relatively large, and the quality requirements for the intermediate shaft are higher, especially the keyway of the intermediate shaft for positioning the transmission teeth. Generally, the width of the keyway is required to reach 18mm, the tolerance is 0.027, the symmetry is 0.2 and the roughness Reach Ra3.2, the traditional milling process can not meet the requirements

Abstract

The invention discloses a light rail intermediate shaft machining process which comprises blank making, normalizing, semifinishing, quenching, finish machining and final inspection. The blank making comprises blank manufacturing and shaft blank rough machining. The semifinishing comprises semi-finish turning, milling a middle section key groove and tooth molding. The finish machining comprises finish turning, milling a flat square, drilling a screw hole, turning threads, grinding a center hole, grinding an external circle, grinding teeth, rough milling an electric spark shaft end key groove. By means of the light rail intermediate shaft machining process, a machining key groove is roughly milled after gear grinding, end products are manufactured through the electric spark shaft end key groove, the key groove size and shape and position accuracy can meet requirements, and requirements for light rail high power output are met.

Description

technical field [0001] The invention relates to a gear shaft processing technology, in particular to a light rail intermediate shaft processing technology. Background technique [0002] The light rail intermediate shaft is an important part of the light rail transmission system. It is used for the transmission of the output power of the power system. There are keyways on the shaft for positioning the transmission teeth. However, the light rail is different from ordinary rail trains. Usually, the design speed is relatively high, and the output torque of the power system Larger, so the torque on the intermediate shaft is also larger, and the quality requirements for the intermediate shaft are higher, especially the keyway of the intermediate shaft for positioning the transmission teeth. Generally, the width of the keyway is required to reach 18mm, the tolerance is 0.027, the symmetry is 0.2 and the roughness Reach Ra3.2, the traditional milling process can not meet the require...
